SPECIFICATION forming part of Letters Patent N0. 481,319, dated August23, 1892.

Application filedseptember 5, 1891- Serial No. 404,919. (No model.)

.To all whom t may concern:

Beit known that I, JAMES WHITE, a citizen of the United States, residingat Cleveland, in the county of Cuyahoga and State of Ohio, have inventedcertain new and useful Improvements in Safe-Locks, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

Figure l is a front elevation of the lock, the inner'wall or cover ofthe casing having been removed. Fig. 2 is a top view looking in thedirection of the arrow l, Fig. l, part of the devices being in sectionon the line yy, Fig. l. Fig. 3 is a section on line Qc, looking in thedirection of the arrow l, Fig. l, this view showing, also, the spindle,dial, and part of the safe door also in section. Fig. 4 is a front Viewof the main driving-wheel. Fig. 5 is a top view of Fig. 4. Fig. 6 is afront View of a loose connecting-wheel. Fig. 7 is a top view of same.Fig. 8 is a rear View of saine. Fig. 9 shows two rings. Fig. 10 is afront elevation, partly broken away, showing the position of parts atthe close of the movement as the 'bolts are shot. Fig. 1l is a similarView showing the position of parts when the combination is being broken.

Like reference-letters indicate like Vparts in all the figures.

A A A is the case or shell, of which A' is the cover or inner Wall,preferably secured in place by screws which pass through its fourcorners and into screw-threaded seats at a a.

B is the spindle, which may be of any approved kind or -patternextending outward through the door and carrying a dial B. (See Fig. 3.)Near its inner end the spindle is threaded at b with a cylindricalsection h', its extreme inner end being preferably threaded to receive anut b2.

O is the main drive-wheel, toothed upon its periphery and screwed rmiyupon the threaded part of the spindle at b.

In a former patent of mine I employ a cam mounted upon and revolvingabout a pivot other than the spindle or arbor, but lying paralleltherewith, for the purpose of lifting the fence out of the notches ofthe tumblers. In my said earlier patent that cam is operated not by thespindle directly, but by means of a series of gears and tumblers whichare interposed between the spindle and the cani and are separated fromthe spindle for the purpose of changing the combination, so that thereis liability when replacing such parts of getting the cam back into thelock in a dierent position relative to the spindle from that which isoccupied before removal,whereas in this invention the cam is rigidlyconnected to and operated by the spindle, so that the spindle and cammaintain a fixed relation as regards their rotating together under allcircumstances.

O (see particularly Figs. 2, 3, and 4) is a cam moving with thedrive-wheel and preferably cast in one piece therewith.

c is a pin projecting inward from the cam to actuate theconnecting-wheel.

The drive-wheel is further provided, preferably, with anout-ward-projecting sleeve or thimble c', fitting closely inside a seatformed therefor in the outer wall of the box or casing, which ispreferably expanded to form a hollow hub A2, so as to provide a longbearing for the sleeve.

D (see particularly Figs. 6, 7, and 8) is the connecting-wheel, mountedloosely on the cylindrical part b of the spindle.

d is a pin projecting from the inner face of the connecting-wheel tothrow the bolt, as will be explained. The outer face of thisconnecting-Wheel has a circularl way or track D with a bridge d', theopposite sides of which serve as abutments to engage with the pin c ofthe drive-wheel, Which enters this sunken Way and travels therein. By anexamination of Figs. 3, 5, and G it will be readily understood that thespindle can make nearly a complete rotation Without actuating theconnectingwheel D; but after it has been turned around until the pin oengages with the bridge a further rotation ot the spindle in the sainedirection will carry with it the connecting-wheel.

E E is the bolt. The part E projects through an end wall of the shell orcasing and is to be connected with boltwork of any usual or approvedconstruction, it being broken oit in the drawings. Itis desirable thatthe thrust of the drag-bar be applied to the bolt as nearly as ispracticable on a line which is coincident with the axis of the bolt andas far forwardthat is to say, toward the vertical bolt-baras ispracticable.

Oompactness of parts is also important in a ICQ lock, and in order toaccomplish satisfactorily both of these ends I have invented a newconstruction of bolt, which, whileV it is particularly adapted for usein a look containing the other novel features to be hereinafterdescribed, is also adapted for use with operating devices which in theirgeneral construction may diier materially from those which I haveillustrated in this patent. Therefore I wish to cover the constructionof the boltirrespective of its combination with any particularappliances for operating it. While the part E projects through thecasing about midway between the front and rear walls, the inner portionE lies, by preference, in a different parallel plane and immediatelyadjacent to the rear wall. (See Fig. 2.) Theinner end of the bolt has ahorizontal slot e with a set screw or guiding-pin e. in the slot tofacilitate the proper guiding of the bolt. At the lower inner corner ofthe bolt it is expanded into a bracket-like projection or arm e2. (SeeFig. 2.) F is the drag-bar. The front end of this drag-bar enters achamber or socket formed for its reception in the part E of the bolt, towhich it is pivoted or otherwise connected so that when it moves endwiseit will carry the bolt with it. A convenient way of connecting theseparts so as to permit the necessary freedom of inovelnentisbyatransverse pivot This drag-bar has an outward-projecting tubular hubor boss F. (See Fig. 2.)

G is an anti-friction wheel. g is a screw-threaded stud passing throughthe antifriction-wheel and into the drag-bar.

In order to provide a very satisfactory bearing for the anti-frictionWheel,I propose to form it with a tubular hub or sleeve, which surroundsthe stud g and ts within the tubular hub or boss F'. (See Fig. 2.)During 'most of the movements of the lock this antifriction wheelperforms no function; but at a particular juncture the cam C engageswith it and lifts the drag-bar up out of the path of the pin d.

H is the fence-lever pivoted at its rear end to the projecting arm e2ofthe bolt, preferably by a pivot-pin or set-screw h. The front end ofthis fence-lever at h is seated loosely in a socket or recess f, formedfor its reception in the inner end of the drag-bar. (See Figs. l and 2.)The fence Z projects downward from the fence-lever, the relation ofparts being substantially that shown in Figs. l, 10, and 11, so thatwhen the fence is riding upon the periphery of the tumblers, thedrag-bar is held up out of the path of the pin d.

Referringparticularly to Fig. 3,Kis a cogged gear having, preferably,the same number of teeth with gear-wheel C and provided upon one facewith a pin lc. L Z Z is a stud projectinginward from one wall of thecase or shell. The part L is cylindrical to receive the cog-wheel K. Thepart Z is preferably screw-threaded, the end Z being, preferably,cylindrical. The part L is shouldered, while the opening through thecog-wheel K is also tenen;v

shouldered to receive a ring k.,fitting` tightly the spindle, so as tohold the cog-wheell in place and prevent its slipping off or getting outof mesh with cog-wheel C inthe absence of the tubular rosette, to bedescribed. To insure a satisfactory frictional grip, I prefer to cutthis ring as shown in Fig. 9. The rosette consists, essentially, ofacylindrical section M with an outwardly-projecting flange or rim M.rlhis rosette is hollow and of such internal conformation as to litquite accurately the stud on which it is mounted-that is to say, theopen end of the recess within the rosette is somewhat enlarged andscrew-threaded to engage with acorresponding thread on the stud. Afterthe rosette is screwed home it is prevented from being accidentallyturned backward by a suitable device, preferablyan eccentric-pin screwedor driven through the rosette into the end of the stud. N N are thetumblers, each rotating independently within certain limits upon therosette. These tumblers have the usual actuating-pins ln, andfence-notches n'. n2n2arethe ordinary spacing-rings interposed betweenthe tumblers,

and after the tumblers and spacing-rings have been strung upon therosette I confine them thereto by means of a clamping-ring m, (see Figs.3 and 9,) so that they will not accidentally slip 0E during theirordinary handling. Thus it will be seen that the spacing-rings andtumblers are secured ku pon the rosette by a detachable fastener,whichis carried by the rosette, and that the gear K is secured in itsposition in the lock by a detachable fastener during the removal andreplacing of the tumblers, these fasteners being secured by friction tothe parts which carry them.

By an examination of Fig. 2it will be readily understood that in 'somepositions of the tumblers the fence will at one end only rest upon theperiphery of either the `outer or inner tumbler, the notches of theother three tumblers being aligned below the fence, andf in suchposition of parts the tendency of the IOO weight of the fence andfence-lever is to twist Referring now to the position ofparts shown i inFig. 1 with the bolts shot, in order to unlock the safe I turn thespindle in opposite directions, accordingy to the combination, until thenotches of the tumbler are all immediately below the fence and inposition .to receive the fence, when of course as the swinging end ofthe fence-lever falls the inner end ofthe drag-bar drops Ainto suchposition that the reverse rotation of the spindle will cause the pin ctov engage with the bridge d and move the pin cZ of the connecting-wheelin the direction indicated by the arrow 2, Fig. 1, into the notch f ofthe drag-bar, when a continned movement of the spindle in the same di-`lrection willfwithdraw the bolts and unlock the safe. Under ordinarycircumstances the pin d of the connecting-wheel will remain in the notchf while the bolts are withdrawn. The bolts may be shot by turning thespindle in the direction indicated by the arrow 3, Figs. l and 10, untilthe pin c engages with the opposite side of the bridge d', when,continuing the rotation, the parts will be moved into the position shownin Fig. 10.

In order to break the combination after the door is thus locked, thespindle may be turned in the direction indicated by arrow 2, Figs. 1,10, and 11, when the pin c will leave the connecting-wheel D standing inthe position shown in Fig. 10, and asA the cam C passes underneath theanti-friction wheel G it will lift the drag-bar out of the path of thepin d and at the same time lift the fence out of the notchesin thetumblers, thus permitting them to be rotated. As the cam passes fromunderneath the anti-friction wheel to the position shown in Fig. 1l, thepin la of the cogwheel K moves the adjacent tumbler so that its notchwill occupy about the position shown in dotted lines at n, Fig. l1, withthe fence resting upon the edge of that tumbler, thus supporting thedrag-bar above the path of the pin cl and permitting perfect freedom ofrotation of the spindle and the wheels mounted thereon, together withthe tumbler, without withdrawing the bolts until by the use of thecombination the notches in the tumblers have all been aligned underneaththe fence, when the drag-bar will drop down into position to engage withthe pin d.

In order to insure a satisfactory operation of the cam in lifting thefence out of the tum-` bler-notches and supporting it there until one ofthe tumblers shall have been rotated far enough to engage with thebridge and hold it up, the outer end of the cam maybe made somewhatWider, as is indicated in dotted lines in Fig. 1.

By providing the bolt with a chamber or socket opening into the lock andpivoting the outer end of the drag-bar in the chamber I am enabled touse such length of drag-bar asy provides -conveniently for the requisiteswing Without unduly increasing the length of the lock. It also enablesme to apply the power for thrusting and withdrawing the bolts in a linewhich is practically parallel with theline of travel of the bolt.
